Una rumbita para ti

The sound loop you are probably listening to right now (if your browser
is able to automagically play MP3) is my modest creation of a short
afro-cuban Rumba Guaguanco with the wonderful open source drum machine Hydrogen which is freely available
from http://hydrogen-music.org.

Unfortunately, Hydrogen
currently does not support non-*NIX operating systems, so Windows users
will still have to wait quite a bit for it to become available for them
too. If you can't wait, just switch to MacOS X or Linux in the meantime.
